Change the look of the dynamic table

Question

I had the dynamic table. I want to change the look of the table. I am facing two challenges
1. To change the background color of header
I tried by overriding the css of the header "table.Tbl th.TblColHdr" but this did not help me.
2. To change the color of the alternate rows
Could any one help me on this regard

for( int i=0;i<records.size();i++)
if((i%2)==0){                                                       %>
     <tr >
     <%}
     else{ %>
     <tr bgcolor="#eeeeee">
<%}
